Adaptive fuzzy guidance law for Intercepting maneuvering targets

A new adaptive fuzzy guidance law is proposed by applying fuzzy control theory to the interception of high-speed maneuvering targets. The problem of guidance law design is converted to feedback control and the command of proportional guidance law and its differential are designed as the inputs of the fuzzy controller. The fuzzy control rules and fuzzy reasoning are expressed by analytical description,which can be calculated easily and is suitable for real-time on-line control. The guidance law can change the fuzzy control rule adaptively according to the strength of maneuvering and the speed of target,therefore it has strong robustness. Numerical simulations show that the proposed guidance law exhibits better performance than traditional proportional guidance law in miss-distance and interception time.
